Description

Technical Field

[0001] This utility model relates to the field of riveting technology, and more specifically, to a riveting device. Background Technology

[0002] In traditional automobile manufacturing, riveting is one of the common methods for connecting body parts. It involves using a rivet gun to pass rivets through two or more layers of material and form a rivet joint on the other side of the material, thereby fixing the parts in place.

[0003] For integrated die-cast parts, due to the special characteristics of the material (such as non-parallelism of the two sides of the hole, fluctuation of the hole surface, and differences in wall thickness) and the structural complexity of large parts, traditional automatic riveting equipment has the following problems when applied:

[0004] 1. After the rivet gun head is attached to the rivet hole, it cannot accurately enter the rivet hole due to fluctuations in the size, angle and position of the rivet hole, resulting in difficulties in initial positioning.

[0005] 2. After the rivet is riveted, the rivet gun shaft is prone to jamming when it is withdrawing, which increases the equipment failure rate and maintenance costs.

[0006] There is currently no effective solution to the technical problems of poor hole positioning accuracy and easy jamming of mandrel withdrawal in existing riveting equipment. Utility Model Content

[0007] The main purpose of this utility model is to provide a riveting device to solve the technical problems of poor hole positioning accuracy and easy jamming of mandrel withdrawal in existing riveting equipment.

[0008] To achieve the above objectives, according to one aspect of the present invention, a riveting device is provided, comprising: a rivet gun; a first driving assembly, the driving end of the first driving assembly being connected to a mounting assembly; a second driving assembly, the fixed end of the second driving assembly being connected to the first driving assembly via the mounting assembly, and the driving end of the second driving assembly being movably connected to the rivet gun; and a control assembly, electrically connected to the rivet gun, the first driving assembly, and the second driving assembly, the control assembly being used to control the rivet gun to perform a riveting action, control the first driving assembly to drive the mounting assembly to move along a first direction, and control the second driving assembly to drive the rivet gun to move along the first direction.

[0009] Furthermore, the control component is used to control the first drive component to move the rivet gun a first preset distance along the first direction so that the rivet gun is located in the first position, and the control component is used to control the second drive component to move the rivet gun located in the first position a second preset distance along the first direction so that the rivet gun is located in the second position.

[0010] Furthermore, the driving end of the second driving component is movably connected to the rivet gun via a floating component. The floating component can drive the rivet gun to swing in a second direction, which is set at an angle to the first direction.

[0011] Furthermore, the floating component includes: a fixed part, which is connected to the drive end of the second drive component; and a movable part, one end of which is hinged to the fixed part, and the other end of which is connected to the rivet gun.

[0012] Furthermore, the rivet gun is movably connected to at least part of the mounting components.

[0013] Furthermore, the mounting components include: a fixed base, the driving end of the first driving component and the fixed end of the second driving component are respectively connected to the fixed base; a fixed rod, the fixed rod is connected to the fixed base, and the axial direction of the fixed rod extends along a first direction; a movable base, the movable base is provided with a through hole, the movable base passes through the through hole and is mounted on the fixed rod, the diameter of the through hole is larger than the outer diameter of the fixed rod, and the rivet gun is connected to the movable base.

[0014] Furthermore, the fixed base is provided with a mounting groove, the fixed rod is connected in the mounting groove, and at least part of the movable base is located in the mounting groove.

[0015] Furthermore, the fixed end of the second drive component is connected to the fixed base via a support frame, and an installation space for mounting the rivet gun is formed between the support frame and the fixed base.

[0016] Furthermore, the mounting base is provided with an extension plate, and the extension plate is provided with a wire hole, through which the rivet gun's cable is threaded.

[0018] Applying the technical solution of this utility model, the fixed end of the second driving component is connected to the driving end of the first driving component through an installation component, and the driving end of the second driving component is movably connected to the rivet gun. During the process of the rivet gun entering the rivet hole, the first and second driving components work together to drive the rivet gun to move along a first direction. The rivet gun can be finely adjusted relative to the driving end of the second driving component to adapt to fluctuations in the size, angle, and position of the rivet hole, thereby allowing the rivet gun to enter the rivet hole and the flange face of the rivet nut to press against the plate to be joined. During the process of the rivet gun exiting after completing the riveting action, the rivet hole may become stuck with the rivet gun shaft due to deformation. The rivet gun can be repositioned relative to the driving end of the second driving component to maintain the optimal contact angle between the rivet gun shaft and the wall of the rivet hole, reducing hard friction between the rivet gun shaft and the wall of the rivet hole, thus allowing the rivet gun shaft to exit smoothly.

[0041] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0042] Combination Figures 1 to 4 As shown, according to a specific embodiment of this application, a riveting device is provided.

[0043] Specifically, the riveting device includes: a rivet gun 10, a first drive assembly 20, a second drive assembly 30, and a control assembly. The drive end of the first drive assembly 20 is connected to a mounting assembly 40. The fixed end of the second drive assembly 30 is connected to the first drive assembly 20 via the mounting assembly 40. The drive end of the second drive assembly 30 is movably connected to the rivet gun 10. The control assembly is electrically connected to the rivet gun 10, the first drive assembly 20, and the second drive assembly 30. The control assembly controls the rivet gun 10 to perform the riveting action, controls the first drive assembly 20 to drive the mounting assembly 40 to move along a first direction, and controls the second drive assembly 30 to drive the rivet gun 10 to move along the first direction.

[0044] In the embodiments of this application, the fixed end of the second drive assembly 30 is connected to the drive end of the first drive assembly 20 through the mounting assembly 40, and the drive end of the second drive assembly 30 is movably connected to the rivet gun 10. During the process of the rivet gun 10 entering the rivet hole, the first drive assembly 20 and the second drive assembly 30 work together to drive the rivet gun 10 to move along the first direction, and the rivet gun 10 can be finely adjusted relative to the drive end of the second drive assembly 30 to adapt to the size, angle, and position fluctuations of the rivet hole, thereby allowing the rivet gun 10 to enter the rivet hole and the flange face of the rivet nut to press against the plate to be connected. During the process of the rivet gun 10 exiting after completing the rivet action, the rivet hole may become stuck with the shaft of the rivet gun 10 due to deformation. The position of the rivet gun 10 relative to the drive end of the second drive assembly 30 can be adjusted so that the shaft of the rivet gun 10 maintains the best contact angle with the wall of the rivet hole, reducing the hard friction between the shaft of the rivet gun 10 and the wall of the rivet hole, thereby allowing the shaft of the rivet gun 10 to exit smoothly. The aforementioned riveting device can adapt to fluctuations in the size, angle, position, and deformation of the rivet hole, so that the rivet gun 10 can be accurately positioned with the rivet hole, thereby smoothly entering and exiting the rivet hole.

[0045] It is understandable that during the manufacturing process of integrated die castings, factors such as material fluidity, mold temperature control, and die casting pressure and speed may cause slight fluctuations in the size of the rivet holes; and due to the draft angle, the hole surface of the integrated die casting has a certain tilt angle with the vertical direction, which in turn causes slight fluctuations in the angle of the rivet holes; and within the same batch of die castings, due to mold wear, cumulative equipment errors, or minor deviations during operation, slight fluctuations in the position of the rivet holes may occur. The aforementioned fluctuations in the size, angle, and position of the rivet holes increase the difficulty of positioning the rivet gun 10 and the rivet holes.

[0046] It should be noted that the first drive assembly 20 and the second drive assembly 30 can drive the rivet gun 10 to move along the first direction simultaneously, or they can drive the rivet gun 10 to move along the first direction sequentially, as long as the rivet gun 10 is fully inserted into the rivet hole.

[0047] In one exemplary embodiment of this application, the control component is used to control the first drive component 20 to move the rivet gun 10 along the first direction by a first preset distance so that the rivet gun 10 is located in the first position, and the control component is used to control the second drive component 30 to move the rivet gun 10 located in the first position along the first direction by a second preset distance so that the rivet gun 10 is located in the second position.

[0048] In this embodiment, the first drive component 20 serves as the main drive component, and its drive stroke is set according to the initial position of the rivet gun 10 and the position of the rivet hole. The second drive component 30 serves as the auxiliary drive component, and its drive stroke is set according to the size, angle, and position fluctuation of the rivet hole to adapt to the stroke fluctuation between the rivet gun 10 and the rivet hole, thereby enabling the rivet gun 10 to fully enter the rivet hole and press the flange face of the rivet nut against the plate to be connected.

[0049] like Figure 1 As shown, the first drive component 20 is a servo electric slide table, and the mounting component 40 is connected to the slider 21 of the servo electric slide table. The second drive component 30 and the rivet gun 10 are both connected to the first drive component 20 through the mounting component 40.

[0050] In one exemplary embodiment of this application, the driving end of the second driving component 30 is movably connected to the rivet gun 10 via a floating component 50. The floating component 50 can drive the rivet gun 10 to swing in a second direction, which is set at an angle to the first direction.

[0051] In the embodiments of this application, different floating components 50 can be replaced according to different riveting conditions to achieve precise alignment between the riveting gun 10 and the riveting hole.

[0052] Furthermore, the floating component 50 includes a fixed part 51 and a movable part 52. The fixed part 51 is connected to the driving end of the second driving component 30, one end of the movable part 52 is hinged to the fixed part 51, and the other end of the movable part 52 is connected to the rivet gun 10. The floating component 50 can be a single-axis hinge, a multi-axis hinge, or a spherical hinge, as long as it ensures that the rivet gun 10 can swing circumferentially in the first direction to adapt to fluctuations in the size, angle, and position of the rivet hole.

[0053] like Figure 1 , Figure 2 As shown, the floating component 50 is a single-axis hinge, including a fixed part 51 and a movable part 52. The fixed part 51 is fixedly connected to the second drive component 30, and the fixed part 51 is provided with a rotating shaft, which is perpendicular to the drive shaft of the second drive component 30. The movable part 52 is sleeved on the rotating shaft of the fixed part 51, and the movable part 52 is dampedly connected to the fixed part 51. Under the action of external force, the movable part 52 can rotate around the rotating shaft of the fixed part 51, and the movable part 52 can move along the axial direction of the rotating shaft. During the riveting action and withdrawal process, the rivet gun 10 can be positioned relative to the drive end of the second drive component 30 to maintain the optimal contact angle between the shaft of the rivet gun 10 and the wall of the rivet hole, reducing the hard friction between the shaft of the rivet gun 10 and the wall of the rivet hole, thereby allowing the shaft of the rivet gun 10 to withdraw smoothly.

[0054] In one exemplary embodiment of this application, the rivet gun 10 is movably connected to at least a portion of the mounting assembly 40. That is, the second drive assembly 30 drives the rivet gun 10 to move on the mounting assembly 40, which serves as a guide and support for the rivet gun 10, thereby making the rivet action of the rivet gun 10 more stable and reliable.

[0055] Furthermore, the mounting assembly 40 includes a fixed base 41, a fixed rod 42, and a movable base 43. The driving end of the first driving assembly 20 and the fixed end of the second driving assembly 30 are respectively connected to the fixed base 41. The fixed rod 42 is connected to the fixed base 41, and the axial direction of the fixed rod 42 extends along a first direction. The movable base 43 is provided with a through hole, and the movable base 43 passes through the through hole onto the fixed rod 42. The diameter of the through hole is larger than the outer diameter of the fixed rod 42. The rivet gun 10 is connected to the movable base 43.

[0056] In the embodiments of this application, the movable seat 43 is mounted on the fixed rod 42 through a through hole. The diameter of the through hole is larger than the outer diameter of the fixed rod 42, so that the movable seat 43 can swing in the circumferential direction of the fixed rod 42 to accommodate the swing of the rivet gun 10 and the floating assembly 50.

[0057] like Figure 2 As shown, the fixed base 41 is connected to the slider 21 of the first drive assembly 20, and the fixed end of the second drive assembly 30 is connected to the fixed base 41. The first drive assembly 20 can drive the fixed base 41 to slide along a first direction, while the fixed base 41 drives the second drive assembly 30 to slide along the first direction. The fixed base 41 is a rectangular structure, and a fixed rod 42 is provided on the fixed base 41. The axis of the fixed rod 42 extends along the length direction of the fixed base 41, and the movable base 43 passes through the fixed rod 42.

[0058] Furthermore, the fixed base 41 is provided with a mounting groove 411, the fixed rod 42 is connected in the mounting groove 411, and at least part of the movable base 43 is located in the mounting groove 411. The mounting groove 411 is provided so that at least part of the movable base 43 is embedded in the mounting groove 411, thereby making the overall structure of the riveting device more compact.

[0059] Furthermore, the fixed end of the second drive assembly 30 is connected to the fixed base 41 via the support frame 60, and an installation space 90 for installing the rivet gun 10 is formed between the support frame 60 and the fixed base 41.

[0060] like Figure 2 , Figure 3 As shown, the support frame 60 has a U-shaped structure, with one end connected to the side of the fixed base 41, forming a U-shaped mounting space 90 between the support frame 60 and the fixed base 41. The rivet gun 10 is located within this mounting space 90. This layout makes the overall structure of the rivet device more compact.

[0061] like Figure 1 , Figure 2 As shown, the mounting base 41 is provided with an extension plate 70, and the extension plate 70 is provided with a wire hole, through which the cable 11 of the rivet gun 10 is inserted.

[0062] The rivet gun 10's cable 11 is threaded through the cable hole to prevent the rivet gun 10's cable 11 from rubbing against other equipment, thereby reducing the risk of damage to the cable 11.

[0063] The rivet gun 10 is connected to the booster cylinder 80 via the pipeline 11. The booster cylinder 80 is used to drive the mandrel of the rivet gun 10 to retract, so that the rivet nut collapses and deforms, thereby achieving the connection with the plate.

[0064] Furthermore, the second drive assembly 30 is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0065] In the embodiments of this application, the second drive component 30 is a cylinder.

[0066] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
